This commit speeds up the tests by calling `MockHost.reset()` in `beforeEach()` instead of destroying the entire language service and creating a new one. The creation of a new language service instance is expensive due to the need to initialize many core Symbols when creating a new program. This speeds ups the test (on my local machine) from 35 secs to 15 secs. PR Close #33200
